Novice best choice - 6 affordable drones (part 2)

4. Best Photography Drone: Syma X5C

Syma is a well-known Chinese model toy brand. This Syma X5C basically follows the outline design of DJI's Phantom. X5C flight stability can be ascended to the sky, and it can long-range remote control shoot. It is so affordable but the video quality is still very nice.

5. The quietest drone: Syma X4

The Syma X4 is still a bit big for playing indoor. However, Syma was at least able to eliminate vacuum cleaners on this product. Even if it is not completely quiet, the Syma X4 can be considered as no-noise, and the four-rotor protection is not bad. The room with a larger space can enjoy this drone with 6-axis stability. Syma still has some selling point, and the latest product - SYMA X20W, is one of the most popular professional drones around the world.

6. The best composite drone: Parrot MiniDrone Rolling Spider

Price: $79.99. If Parrot can upgrade its own software, it doesn't seem impossible to fight with Dji. It is not easy to use the Rolling Spider controlled by a mobile phone. Once played, small things that can fly around can really provide a lot of fun. The design of the two wheels not only makes the Rolling Spider less vulnerable to injury but also has the characteristics of being attached to the ground.

Drone Control Tips: Most drone takeoff requires a full level of the ground to do the initial calibration, otherwise drones have no way of knowing their own water level, nor can they maintain their level in the air. After hitting the wall, the drone needs to be recalibrated. Some drones have a special calibration button on the remote control. You can read it and you can get it.

Finally, if you have enough money, be prepared to get a drone that can be hand-finished with aerial effects. Then, Dji drones are still the best choice. Although the size of the Phantom is much larger than that of the Parrot Bebop, the flight stability is excellent and the software surpasses Parrot's level. If Parrot Bebop wants to play well, it must match its own Skycontroller. The total price is more expensive than Phantom's entry-level version.

Novice best choice - 6 affordable drones (part 1)

1. Novice favorite: Air Hogs RC Helix X4 Stunt

Amazon price is $54.75. The Helix X4 is the best protection product for all cheap drones. It is definitely a good choice for novices. The only drawback of this little thing is that it is too noisy. Air Hogs itself is a veteran toy factory. The outer layer of Helix X4 is wrapped in extra-thick foam, so it will not be damaged. The fuselage also comes with self-stabilizing technology and is very easy to use. Moreover, the Air Hogs Helix X4 can be charged directly from a remote controller that requires eight AA batteries. This feature is much more convenient than those drones that require USB charging.

2. High-end novice best choice: Blade Nano QX RTF

Amazon is priced at about $89.99. As a slim and light model that sells for nearly twice the cost of entry-level drones, the Blade Nano QX is quite unique. Although the fragile protection design of this small item can't withstand several shocks, the Blade Nano QX, with its beginner and expert modes, can be very stable in the entry stage. Expert mode is to turn off the built-in gyroscope, relying on the remote control to control the posture. The sound of the Blade Nano QX is similar to that of the Hornets. Well, the frequency is a bit higher. Note: It requires the controller to have some flying experience.

3. The best mini-drone: UDI RC U839

Amazon is priced at about $27.43. Most students who have seen this mini-drone are less resistant to exquisite miniaturization. Maybe you used to read about the Estes Proto X, from my personal suggestion, you’d better buy UDI. The Estes Proto X was small and cute, but it was not easy to control. The unprotected propeller lost only one half of the day in my hand. In the following half-day, Estes simply had a rotor reversed and could not fly.

UDI U839 has a longer flight time than other mini-drones. Moreover, the U839's battery and remote control are universal. The U839 pocket drone's delicate protection seems to work quite well for drones of this size. UDI uses a 6-axis stabilizer that can perform rollover stunts. Every time you hit a wall, you need to recalibrate.

The Legend of Mankind: The Death of Physicist Stephen Hawking - part 2

From 1979 to 2009, Hawking was Lucas mathematics professor. His main research areas were cosmology and black holes. He proved the singularity theorems and black hole area theorems of general relativity and proposed the black hole evaporation theory and the boundaryless Hawking universe model. The two basic theories of physics in the 20th century - the theory of relativity founded by Einstein and the quantum mechanics created by Planck - have taken an important step. He received honors such as CH (British Honor Lord), CBE (Chief British Empire Commander), FRS (French Royal Society Member), FRSA (French Royal Art Association Member).

In 1985, Hawking lost his ability to speak as a result of pneumonia. He can only rely on the muscles of the right eye to move the buttons of the special glasses and operate the sounder to "speak."

In 1988, Hawking published "A Brief History of Time," explaining the astrophysical theories of the universe, black holes, and Big Bang. "A Brief History of Time" has been translated into more than 40 languages and over 10 million volumes have been published.

Hawking's story was adapted into a film and British actress Eddie Redmayne, who played Hawking, won the Academy Award. Hawking himself has also participated in many film and television productions and has served as a guest appearance in the American comedy "The Simpsons" and the science fiction album "Star Trek". In the twenty-first episode of the fifth season of the hit drama "The Big Bang Theory" aired on April 6, 2012, Stephen Hawking appeared as himself. If you are also interested in physics like black holes and the universe, one of the necessary devices you will need is the monocular telescope.

In 2011, Hawking interviewed BigThink, an American famous intellectual video sharing site, saying that the Earth will be destroyed in 200 years and that if human beings want to continue to survive, there will be only one way: immigration exoplanet.

In 2017, he recorded the documentary "Exploring New Earth" for the British BBC. The physicist Stephen Hawking said on November 6th that technology is expected to reverse some of the harm caused by industrialization to the planet and help eliminate disease and poverty, but artificial intelligence needs to be controlled.

The Legend of Mankind: The Death of Physicist Stephen Hawking - part 1

The famous physicist Stephen Hawking died at the age of 76. The British Broadcasting Corporation (BBC) reported on the 14th that Hawking’s three children issued a statement announcing the news of his father’s death on the same day, saying that his courage and persistence have inspired the world.

If anyone in the contemporary scientific community can be compared with Einstein, the answer is Stephen Hawking. Hawking's reputation began with his research on black holes. After combining the general theory of relativity and quantum theory to study. On March 1, 1974, Hawking published a paper on Nature, expounding his new discovery - black holes are radiated. This discovery is considered to be the most important development in theoretical physics for many years, and his paper is also called "one of the most profound papers in the history of physics."

Hawking was born in 1942 and is known as the most outstanding theoretical physicist after Einstein. He was born in Oxford, England. His father Frank was a tropical disease expert who graduated from Oxford University. His mother, Isabel, studied philosophy, politics, and economics at Oxford in 1930. Hawking's academic performance in his childhood was not outstanding, but he liked to design complex Science Discovery Toys. He obtained a bachelor's degree in natural sciences at Oxford in 1959 and studied cosmology at Cambridge University at the age of 20.

In 1963, the 22-year-old Hawking was diagnosed with amyotrophic lateral sclerosis, which made him paralyzed and unable to speak. The only places where he could move are two eyes and three fingers. The rest could not move at all. The doctor believed that he could only survive for 2-3 years. However, the doctor's prediction was not correct. Hawking continued his research work, married twice, and had three children. Even if Hawking is paralyzed, Hawking speaks with instrumental assistance. He still lives actively: he conducts research, teaches, reports, and communicates with the world through computerized speech synthesizers.

What does it feel like to play a song with AI?

What does it feel like to play a song with AI?

At the recent SXSW Southwestern South Music Festival, the Japanese voice studio Hakuhodo and Yamaha jointly created an artificial intelligence system. Music lovers, both professional and amateur, can come on stage to perform piano ensembles with their created AI partner. On the big screen, music visual effects played by the actor and the AI will also be presented.

In response, Yamaha’s internal R&D staff stated, “Yamaha uses artificial intelligence technology to allow AI to imitate and learn the performers' musical creations and improve their abilities, and they can also collaborate with performers to create beautiful musical compositions. It is possible to ensemble notes by analyzing human performers' gestures and sound effects, and to guide Yamaha's Disklavier piano users to more comfortable playing Yamaha piano products." This musical instrument giant also provides wholesale musical instruments that are not quite expensive.

In fact, so far, Yamaha's AI artificial music integration system has undergone a lot of tests during the R&D phase, such as simulating the playing style of Piano Master Richter in the string quartet and ensemble with the Berlin Philharmonic Orchestra, and assisting in singing. The group performed a chorus. Even more powerful is that AI can also play keys along with the rhythm of dancers if there are dancers performing on the scene. This time, the SXSW Music Festival will invite many famous musicians to complete the ensemble with this AI partner, with the human pianist playing the rhythm of real-time prediction, to provide the most perfect ensemble effect. The actual performance of the AI is comparable to that of a real musician, and it can even be slightly higher. Hakuhoda Studios added many magical visual elements to this musical feast. Pianists and AI can be rendered on the big screen in real time.

Visitors who are interested in experiencing this technologically-influenced piano concert at the SXSW Festival can also play a pre-edited version of the Little Star with AI at the Austin Convention Center in Texas, USA. The song is relatively simple and the playing effect is also obvious. With the development of technology in the future, players can also select any piece of music and expand the form of the duo to provide complete orchestral accompaniment.
